Go out at night and see what is eating the seedlings. Sparrows eat my lettuce the first couple of months of the year. I have a bird trap now. They also eat the heart out of my snow peas certain times of the year. Work out how to put a border around each plant or the whole block of lettuce. Like a 90mm pipe 100mm long and put oil or grease or Vaseline on the outside. Or look up similar things on the internet for slugs, snails etc. Or build a frame and cover with shade cloth.

Hi I'm totally new to any kind of growing and am currently experimenting with a hydroponic setup But having trouble getting lettuce seeds started. Had no problems with previous 3 attempts but this time the seeds are doing nothing. Not sure if its the time of year or something else........ Any advice would be appreciated GD

Wait until this present cold weather passes and we have warmer nights. With spring only a week or two away temps should start to rise a bit, then try again. Lettuce need light to germinate. Keep soil moist and use a fine light watering.

Hi Karen, I recently bought Butter lettuce seeds from my local Bunnings! And have had great crops right through winter, just direct sew into garden and pick young leaves to thin them out. I'm in Perth. Regards Nicole

It is called buttercrunch lettuce. Try BOONDIE seeds on the internet.

My apologies - I looked up Boondie seeds and they also have butterhead - there may be more. A suggestion - line a Styrofoam box with some paper or shade cloth on the bottom and fill with soil/potting mix/compost and plant the seeds very close - like 100-200 seeds. Water very carefully until they germinate and keep moist. When they grow you can just trim a few off above the heart of the plant and then let them regrow. Just cut enough at a time for a meal or 3.

You have indicated temperate and it says plant all year. Cool / Mountain is Sept to May. Do you receive all day sun. They need lots of sun. If still no good suggest you grow another variety.

Hi Tara, the planting guide says you can plant lettuce in the garden now but how well it does may depend on where you are located and how hot your weather will be. I had a similar dilemma because I live in SW Qld and we have really hot long summers. I tried sowing some seeds in January but they didn't germinate and I read in a gardening book that they will not germinate in temps over 28 degrees. The same book also mentioned that it is possible to germinate lettuces in the fridge so that is what I have done :-D. I now have cute little lettuce seedlings almost ready to plant into the garden (2 loose leaf varieties) and after a couple of cooler days in the last week I have found some of my previous lettuces have self seeded and I have more plants coming up in the garden! I guess i will find out if they survive or not! The biggest danger in the hot temps is that the plants may go to seed quickly meaning less lettuce to eat. If planting lettuces this time of year it is important to give them plenty of shade and lots of water on the hot days. If the plants still go to seed quickly it may be just too hot for them and you can learn for next year. As far as which varieties to choose you should avoid heading lettuces like icebergs because I have heard you won't get a good head on them if it is too hot. I am not an expert - I have only been growing veg for about a year - but you should consider doing what I did and buy some mixed lettuce seedlings from your nearest garden shop and keeping the seeds from the varieties you like the best! Alternatively if any of your friends grow their own you can ask them for a taste or any spare seeds. If you already have some seeds you can always give them a try and see what works best!! If there are any more experienced gardeners out there feel free to correct me if I am wrong!
